"What are your seizures telling you?": A therapeutic tool for functional seizures.

BACKGROUND: Understanding illness representations is considered important for improving health outcomes, yet how people with functional seizures reflect on the possible psychological function of their seizures has not been studied. METHODS: A semi-structured interview comprising open and closed questions was administered to 99 participants with a documented diagnosis of functional seizures. One item, 'What do you think your functional seizure symptoms are telling you?" sought to explore how individuals reflect on the possible function of their seizures. Qualitative analysis using NVivo comprised thematic content analysis of responses to the question, and pattern analysis, to determine association with diagnosis acceptance, and openness to a possible psychological aetiology. RESULTS: Most patients (88 %) readily interpreted their seizures in response to this question. We identified one major theme, with the majority of participants interpreting seizure symptoms as an enforced hiatus. Two minor themes were identified: personal growth and contempt. Subthemes were identified within both the enforced hiatus (stop, slow down, relax) and personal growth (self-care, self-development, acceptance) themes. Individuals who did not accept the diagnosis of functional seizures referenced seizures with contempt towards the self or answered, 'don't know'. Respondents who did not know also tended to reject a psychological basis for their seizures in contrast to those who discussed themes of enforced hiatus, personal growth, and contempt. CONCLUSIONS: Responses provide valuable insight into how individuals reflect on their condition in a non-acute setting. Themes can serve as a foundation for future therapeutic discussions and patient-centred communication strategies to build a mutual understanding of the potential function of physical symptoms regardless of whether a psychological basis for them is accepted or not. What is already known on this topic: Outcomes for functional seizures are generally poor and often attributed to patients rejecting psychiatric care or not accepting the diagnosis. WHAT THIS STUDY ADDS: This study is the first to explore patient conceptualisations of the possible function of their functional seizures as a therapeutic tool for understanding the condition. How this study might affect research, practice, or policy: Findings may provide a basis for improved clinician-patient relationships, treatment engagement, and more targeted interventions for people with functional seizures.

Breathing control training for functional seizures: A multi-site, open-label pilot study.

There are no well-validated treatments for functional seizures. While specialist psychotherapy is usually recommended, the evidence for its benefit is qualified, and it can be difficult to obtain. Given the association between hyperventilation and functional seizures we explored an alternative modality, breathing control training, in a multi-site open label pilot trial. Participants with functional seizures over the age of 16 received an hour of breathing training from a respiratory physiotherapist, with a half-hour booster session a month later. Seizure frequency and Nijmegen scores (a measure of hyperventilation) were reported at baseline and follow-up, 3-4 months later. Eighteen subjects were recruited, and 10 completed follow-up. Seven of these 10 had improved seizure frequency, and 3 did not (Wilcoxon signed rank test, p = 0.09), with seizure frequency correlating with Nijmegen score (Spearman's rank correlation = 0.75, p = 0.034). The intervention was well tolerated, with no adverse events reported. These preliminary results support a potentially new approach to treating functional seizures that should prove cost-effective and acceptable, though require confirmation by a randomised controlled trial.

Childhood trauma in patients with epileptic vs nonepileptic seizures.

OBJECTIVE: Childhood trauma has been implicated as a risk factor for the etiology of psychogenic nonepileptic seizures (PNES). Relatively little attention has been paid to whether profiles of specific trauma types differ between patients with epilepsy and PNES. Investigating childhood trauma profiles in these patient groups may identify psychological vulnerabilities that predispose to developing PNES, and aid early diagnoses, prevention, and treatment. METHODS: Data were collected from two cohorts (nRetrospective  = 203; nProspective  = 209) admitted to video-electroencephalography (EEG) monitoring units in Melbourne Australia. The differences in Childhood Trauma Questionnaire domain score between patient groups were investigated using standardized effect sizes and general linear mixed-effects models (GLMMs). Receiver-operating characteristic curves were used to investigate classification accuracy. RESULTS: In the retrospective cohort, patients diagnosed with PNES reported greater childhood emotional abuse, emotional neglect, physical abuse, sexual abuse, and physical neglect relative to patients with epilepsy. These differences were replicated in the prospective cohort, except for physical abuse. GLMMs revealed significant main effects for group in both cohorts, but no evidence for any group by domain interactions. Reported sexual abuse showed the best screening performance of PNES, although no psychometric scores were adequate as isolated measures. SIGNIFICANCE: Patients with PNES report a greater frequency of childhood trauma than patients with epilepsy. This effect appears to hold across all trauma types, with no strong evidence emerging for a particular trauma type that is more prevalent in PNES. From a practical perspective, inquiry regarding a history of sexual abuse shows the most promise as a screening measure.

Improving the treatment of functional seizures through a public specialist outpatient clinic.

OBJECTIVES: We performed an audit of the first 12 months of clinical operations to assess the feasibility of a newly established public outpatient clinic for the assessment and treatment of functional (psychogenic nonepileptic) seizures (FS). METHOD: Clinical notes for the first 12 months of the FSclinic weresystematicallyreviewed with data compiled onreferral pathways, clinic attendance, clinical features, treatments, and outcomes. RESULTS: Of eighty-two new FS patients referred to the clinic, over 90% attended. Patients were diagnosed with FS after comprehensive epileptological and neuropsychiatric review, mostly with typical seizure-like episodes captured during video-EEG monitoring, and most accepted the diagnosis. Most had FS at least weekly, with little sense of control and significant impairment. The majority of individuals had significant psychiatric and medical comorbidity. Predisposing, precipitating, and perpetuating factors were readily identified in >90% of cases. Of 52 patients with follow-up data within12 months, 88% were either stable or improved in terms of the control of their FS. CONCLUSION: The Alfred functional seizure clinic model, the first dedicated public outpatient clinic for FS in Australia, provides a feasible and potentially effective treatment pathway for this underserved and disabled patient group.

Principles for delivering improved care of people with functional seizures: Closing the treatment gap.

Patients diagnosed with functional (psychogenic nonepileptic) seizures have similar or greater levels of disability, morbidity and mortality than people with epilepsy, but there are far fewer treatment services. In contrast to epilepsy, the current understanding of pathophysiological mechanisms and the development of evidence-based treatments for functional seizures is rudimentary. This leads to high direct healthcare costs and high indirect costs to the patient, family and wider society. There are many patient, clinician and system-level barriers to improving outcomes for functional seizures. At a patient level, these include the heterogeneity of symptoms, diagnostic uncertainty, family factors and difficulty in perceiving psychological aspects of illness and potential benefits of treatment. Clinician-level barriers include sub-specialism, poor knowledge, skills and attitudes and stigma. System-level barriers include the siloed nature of healthcare, the high prevalence of functional seizures and funding models relying on individual medical practitioners. Through the examination of international examples and expert recommendations, several themes emerge that may address some of these barriers. These include (1) stepped care with low-level, brief generalised interventions, proceeding to higher level, extended and individualised treatments; (2) active triage of complexity, acuity and treatment readiness; (3) integrated interdisciplinary teams that individualise formulation, triage, and treatment planning and (4) shared care with primary, emergency and community providers and secondary consultation. Consideration of the application of these principles to the Australian and New Zealand context is proposed as a significant opportunity to meet an urgent need.

Multidimensional psychopathological profile differences between patients with psychogenic nonepileptic seizures and epileptic seizure disorders.

OBJECTIVE: Early differential diagnosis of psychogenic nonepileptic seizures (PNES) and epileptic seizures (ES) remains difficult. Self-reported psychopathology is often elevated in patients with PNES, although relatively few studies have examined multiple measures of psychopathology simultaneously. This study aimed to identify differences in multidimensional psychopathology profiles between PNES and ES patient groups. METHOD: This was a retrospective case-control study involving patients admitted for video-EEG monitoring (VEM) over a two-year period. Clinicodemographic variables and psychometric measures of depression, anxiety, dissociation, childhood trauma, maladaptive personality traits, and cognition were recorded. Diagnosis of PNES or ES was determined by multidisciplinary assessment and consensus opinion. General linear mixed models (GLMMs) were used to investigate profile differences between diagnostic groups across psychometric measures. A general psychopathology factor was then computed using principal components analysis (PCA) and differences between groups in this 'p' factor were investigated. RESULTS: 261 patients (77 % with ES and 23 % with PNES) were included in the study. The PNES group endorsed greater symptomatology with GLMM demonstrating a significant main effect of group (η2p = 0.05) and group by measure interaction (η2p = 0.03). Simple effects analysis indicated that the PNES group had particularly elevated scores for childhood trauma (ß = 0.78), dissociation (ß = 0.70), and depression (ß = 0.60). There was a high correlation between psychopathology measures, with a single p factor generated to explain 60 % variance in the psychometric scores. The p factor was elevated in the PNES group (ß = 0.61). ROC curve analysis indicated that these psychometric measures had limited usefulness when considered individually (AUC range = 0.63-0.69). CONCLUSION: Multidimensional psychopathological profile differences exist between patients with PNES and ES. Patients with PNES report more psychopathology overall, with particular elevations in childhood trauma, dissociation, and depression. Although not suitable to be used as a standalone screening tool to differentiate PNES and ES, understanding of these profiles at a construct level might help triage patients and guide further psychiatric examination and enquiry.

Clinical predictors of discordance between screening tests and psychiatric assessment for depressive and anxiety disorders among patients being evaluated for seizure disorders.

OBJECTIVE: This study was undertaken to identify factors that predict discordance between the screening instruments Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) and Generalized Anxiety Disorder scale (GAD-7), and diagnoses made by qualified psychiatrists among patients with seizure disorders. Importantly, this is not a validation study; rather, it investigates clinicodemographic predictors of discordance between screening tests and psychiatric assessment. METHODS: Adult patients admitted for inpatient video-electroencephalographic monitoring completed eight psychometric instruments, including the NDDI-E and GAD-7, and psychiatric assessment. Patients were grouped according to agreement between the screening instrument and psychiatrists' diagnoses. Screening was "discordant" if the outcome differed from the psychiatrist's diagnosis, including both false positive and false negative results. Bayesian statistical analyses were used to identify factors associated with discordance. RESULTS: A total of 411 patients met inclusion criteria; mean age was 39.6 years, and 55.5% (n = 228) were female. Depression screening was discordant in 33% of cases (n = 136/411), driven by false positives (n = 76/136, 56%) rather than false negatives (n = 60/136, 44%). Likewise, anxiety screening was discordant in one third of cases (n = 121/411, 29%) due to false positives (n = 60/121, 50%) and false negatives (n = 61/121, 50%). Seven clinical factors were predictive of discordant screening for both depression and anxiety: greater dissociative symptoms, greater patient-reported adverse events, subjective cognitive impairment, negative affect, detachment, disinhibition, and psychoticism. When the analyses were restricted to only patients with psychogenic nonepileptic seizures (PNES) or epilepsy, the rate of discordant depression screening was higher in the PNES group (n = 29, 47%) compared to the epilepsy group (n = 70, 30%, Bayes factor for the alternative hypothesis = 4.65). SIGNIFICANCE: Patients with seizure disorders who self-report a variety of psychiatric and other symptoms should be evaluated more thoroughly for depression and anxiety, regardless of screening test results, especially if they have PNES and not epilepsy. Clinical assessment by a qualified psychiatrist remains essential in diagnosing depressive and anxiety disorders among such patients.

Psychiatric and cognitive characteristics of older adults admitted to a Video-EEG monitoring (VEM) unit.

OBJECTIVE: To compare the clinical, psychiatric, and cognitive characteristics of older with younger patients presenting to a video-EEG monitoring (VEM) unit. METHOD: This was a retrospective case-control study involving patients admitted for VEM over a two-year period (from April 2018 to April 2020) at two comprehensive epilepsy units. Patients were categorized into an older (≥60 years) and a younger (<60 years) group. Younger patients were individually matched to older adults to form a matched younger group. Diagnosis was determined by a consensus opinion of epileptologists, neurologists, and neuropsychiatrists. The main diagnostic categories were epilepsy, psychogenic nonepileptic seizures (PNES), and 'other' diagnosis (non-diagnostic and other nonepileptic diagnoses). Clinical psychiatric diagnoses were obtained from neuropsychiatric reports. Objective cognitive function was measured with the Neuropsychiatry Unit Cognitive Assessment Tool (NUCOG). Subjective cognitive function was assessed using the Quality of Life in Epilepsy Inventory-89 (QOLIE-89) cognitive subscales. RESULTS: Five-hundred and thirty three patients (71 older, 462 younger) aged 16-91 years were admitted to the VEM unit during the study period. There was a diagnosis of focal epilepsy in 55% of the older group and 48% of the younger group, generalized epilepsy in 3% of the older group and 10% of the younger group, and 'other' in 32% of the older group and 19% of the younger group. Ten percent (2 males and 5 females) of the older group were diagnosed with PNES compared to 22% of the younger group (p = 0.016). A depressive disorder was diagnosed in 34% of the older group and 24% of the younger group (p = 0.20). An anxiety disorder was diagnosed in 15% of the older group and 25% of the younger group (p = 0.15). Mild neurocognitive disorder was more common in the older group (34%) compared to the matched younger group (34% vs 3%, p < 0.001). The older group had lower mean NUCOG scores compared to the matched younger group (79.49 vs 87.73, p = <0.001). There was no evidence for a relationship between mean NUCOG score and overall subjective cognitive difficulties for the older group (r = 0.03, p = 0.83). Among older adults, those diagnosed with PNES had more experiences of childhood trauma. Measures of dissociation, depression, or general anxiety did not differ between PNES and non-PNES diagnoses in the older group. CONCLUSION: Psychiatric comorbidities are common among older adults admitted for VEM. The psychological impact of epilepsy and risk factors for PNES seen in younger patients are also applicable in the older group. The older group demonstrated more cognitive impairments than the younger group, although these were usually unrecognized by individuals. Older adults admitted to VEM will benefit from psychiatric and neuropsychological input to ensure a comprehensive care approach to evaluation and management.

Adverse events related to antiepileptic drugs.

OBJECTIVE: Adverse events (AEs) related to antiepileptic drugs (AEDs) may interfere with adequate dosing and patient adherence, leading to suboptimal seizure control, and relatedly, increased injuries, hospitalizations, and mortality. This study investigated the clinicodemographic factors associated with AEs related to AEDs as reported by the Liverpool Adverse Events Profile (LAEP), and explored the ability of LAEP to discriminate between epilepsy and psychogenic nonepileptic seizures (PNES). We hypothesized that female sex, mood disorders, AED-polytherapy, duration, and severity of epilepsy are associated with increased endorsement of AEs related to AEDs, and that endorsement of AEs related to AEDs would significantly differ between epilepsy and PNES patients. METHODS: We prospectively enrolled adult patients admitted to two inpatient video-electroencephalogram monitoring units. Clinicodemographic variables and psychometric measures of depression, anxiety, and cognitive function were recorded. Patient-reported AE endorsement was obtained using the LAEP, which was reduced to four latent domains using exploratory structural equation modeling. General linear models identified variables associated with each domain. Logistic regression determined the ability of LAEP scores to differentiate between epilepsy and PNES. RESULTS: 311 patients met inclusion criteria. Mean age was 38 years and 56% of patients were female. Network analysis demonstrated strong relationships between depression and anxiety with physical, sleep, psychiatric, and dermatological AE endorsement. Depression, female sex, and AED polytherapy were associated with greater AE endorsement. Epilepsy, compared to PNES, was associated with lower AE endorsement. Fewer prescribed AEDs and greater reported physical AE endorsement were associated with PNES diagnosis. SIGNIFICANCE: There is a strong relationship between patient-reported AEs and psychiatric symptomatology. Those with PNES paradoxically endorse greater physical AEs despite receiving fewer AEDs. Patients who endorse AEs in clinical practice should be screened for comorbid depression or anxiety and treated accordingly.

Burnout and psychological distress amongst Australian healthcare workers during the COVID-19 pandemic.

OBJECTIVE: To examine psychological distress in healthcare workers (HCWs) during the COVID-19 pandemic in April-May 2020. METHODS: A cross-sectional survey examining demographic, employment and mental health characteristics of HCWs in a large metropolitan hospital in Australia. RESULTS: HCWs showed significant symptoms of moderate-severe level depression (21%), anxiety (20%) and posttraumatic stress disorder (PTSD; 29%), associated with burnout, prior psychiatric history, profession and resilience. CONCLUSION: Despite low levels of COVID contact, moderate to high levels of psychological distress were reported. Continued monitoring and support for HCWs' mental well-being is warranted as the COVID-19 pandemic develops.

Cognitive relevance of the community structure of the human brain functional coactivation network.

There is growing interest in the complex topology of human brain functional networks, often measured using resting-state functional MRI (fMRI). Here, we used a meta-analysis of the large primary literature that used fMRI or PET to measure task-related activation (>1,600 studies; 1985-2010). We estimated the similarity (Jaccard index) of the activation patterns across experimental tasks between each pair of 638 brain regions. This continuous coactivation matrix was used to build a weighted graph to characterize network topology. The coactivation network was modular, with occipital, central, and default-mode modules predominantly coactivated by specific cognitive domains (perception, action, and emotion, respectively). It also included a rich club of hub nodes, located in parietal and prefrontal cortex and often connected over long distances, which were coactivated by a diverse range of experimental tasks. Investigating the topological role of edges between a deactivated and an activated node, we found that such competitive interactions were most frequent between nodes in different modules or between an activated rich-club node and a deactivated peripheral node. Many aspects of the coactivation network were convergent with a connectivity network derived from resting state fMRI data (n = 27, healthy volunteers); although the connectivity network was more parsimoniously connected and differed in the anatomical locations of some hubs. We conclude that the community structure of human brain networks is relevant to cognitive function. Deactivations may play a role in flexible reconfiguration of the network according to cognitive demand, varying the integration between modules, and between the periphery and a central rich club.

Utility of the Stanford Integrated Psychosocial Assessment for Transplant in predicting outcomes before and after lung transplantation.

BACKGROUND: Optimizing donor use and achieving maximal survival following lung transplantation (LTx) require a pretransplant assessment that identifies clinical, physiological, and psychosocial patient factors associated with both poor and optimal post-LTx survival. We examined the utility of a psychosocial tool, the Stanford Integrated Psychosocial Assessment for Transplant (SIPAT), to identify patient suitability for LTx, as well as its association with clinical outcomes before and after LTx. METHODS: This was a retrospective single-center study analyzing LTx assessment clinical variables (age, gender, diagnosis, functional capacity, nutrition, renal function), with a particular focus on the utility of the SIPAT score, to predict patient suitability for LTx. The same variables were analyzed against LTx waitlist mortality, as well as post-LTx survival. RESULTS: Over an 8-year period dating from December 2012, 914 patients (male 54.4%, mean age 55.2 years) underwent LTx assessment. Patients declined for LTx (n = 152, 16.6%) were older and had reduced functional capacity, nutritional markers, and renal function but had a higher SIPAT score. Once listed for LTx, a higher SIPAT score was not associated with waitlist mortality or reduced post-LTx survival. CONCLUSIONS: The SIPAT tool measures psychosocial suitability for transplantation that can be incorporated into a standardized assessment of LTx suitability. While patients with higher SIPAT score were more likely to be declined for LTx, the SIPAT score did not predict outcome in transplanted patients. A subgroup of patients with high SIPAT scores were successfully transplanted, suggesting that unfavorable psychosocial variables are potentially modifiable with a well-resourced multidisciplinary LTx team.

Validation of the Seizure-Related Impact Assessment Scale (SERIAS): a study protocol.

INTRODUCTION: This study aims to validate the Seizure-Related Impact Assessment Scale (SERIAS). This novel patient-reported outcome measure (PROM) compares the 'trade-off' between seizures and treatment-related adverse effects, and measures epilepsy disability qualitatively and quantitively. It fills an important gap in PROMs for epilepsy clinical trials and practice. METHODS AND ANALYSIS: Adults with epileptologist-confirmed epilepsy from two Australian Epilepsy Centres are being recruited. People with functional seizures, or who are unable to self-complete English-language validated instruments are excluded. Participants providing informed consent are invited to complete questionnaires at baseline, 3 and 6 months later. SERIAS includes five questions that ask about the number of days per month that seizures or treatment-related adverse effects partially or fully impact work/home/school and family/social/non-work activities, as well as a visual analogue scale regarding epilepsy-related disability. SERIAS is completed alongside seven internationally validated instruments measuring treatment-related adverse effects, mood disorders and quality of life. Target recruitment is n=100, ensuring>50 people complete all questionnaires at all timepoints. Comprehensive psychometric analysis will be performed. Convergent validity will be investigated using bivariate correlations with relevant measures. Reliability will be investigated using Cronbach's alpha, McDonald's omega and test-retest correlation coefficients. SERIAS will be a novel PROM for epilepsy clinical trials and practice. ETHICS AND DISSEMINATION: Multisite ethics approval was granted by the Alfred Health Ethics Committee (HREC 17/23). Results of this study will be disseminated through publication in peer-reviewed journals and presentations at scientific conferences. TRIAL REGISTRATION NUMBER: ACTRN12623000599673.

Comparative effectiveness of digital mental healthcare models for adults with epilepsy: A study protocol of a randomized controlled trial.

OBJECTIVE: Mental health complaints are prevalent among people with epilepsy, yet there are major barriers that prevent access to psychological care, including high out-of-pocket costs and a lack of accessible specialized services. The purpose of the current study is to examine the comparative efficacy, acceptability, cost-effectiveness, and long-term outcomes of a digital psychological intervention when delivered under two models of care (i.e., guided vs. unguided) in supporting the mental health and functioning of adults with epilepsy. METHOD: Approximately 375 participants across Australia will be enrolled. Eligible participants will have a confirmed diagnosis of epilepsy, experience difficulties with their emotional health, be at least 18 years of age, and live in Australia. Participants will be randomized (2:2:1) to receive the Wellbeing Neuro Course, a 10-week internet-delivered program, with (i.e., guided) or without guidance by a mental health clinician (i.e., unguided), or be allocated to a treatment-as-usual waiting-list control group. Participants will complete online questionnaires at pre-, post-treatment, and 3- and 12-month follow-up and consent to have their data linked to their medical records to capture healthcare system resource use and costs. ANALYSIS: Primary outcome measures will be symptoms of depression and anxiety. A cost-utility analysis will be undertaken using the Australian healthcare system perspective and according to current economic evaluation guidelines. Resource use and costs to the healthcare system during the study period will be captured via data linkage to relevant administrative datasets in Australia. SIGNIFICANCE: The results of this trial will provide important data concerning the relative outcomes of these different models of care and will inform the integration of digital psychological interventions translation into healthcare services. ETHICS AND DISSEMINATION: The Human Research Ethics Committee of Macquarie University approved the proposed study (Reference No: 520231325151475). The results will be disseminated through peer-reviewed publication(s). ANZCTR TRIAL REGISTRATION NUMBER: ACTRN12623001327673. PLAIN LANGUAGE SUMMARY: This study seeks to find out if a 10-week online psychological treatment can improve the mental health and well-being of Australian adults with epilepsy. Around 375 participants will be randomly assigned to different groups: one will receive treatment with guidance from mental health clinician (guided group), one without guidance (unguided group), and one starting later (waiting control group). All participants will fill out the same outcome measures online. The main goal of this research is to compare these groups and assess how well the treatment works in improving mental health outcomes.

Content or context? A study protocol for a three-arm parallel randomised controlled trial of Re-PROGRAM, a brief internet-based intervention for patients with functional seizures.

INTRODUCTION: Functional seizures (FS) mimic epilepsy but are not caused by epileptic electrical activity in the brain and are believed to have a psychological origin. There is a well-documented gap between the needs of patients with FS and available therapeutic resources. While there is potential for reducing seizure burden in patients via psychosocial intervention, there is no evidence-based care pathway or consistent availability of treatment and no effective pharmacological treatment. The objective of this study is to investigate the clinical efficacy and tolerability of a novel internet-based intervention in reducing seizure frequency. METHODS AND ANALYSIS: A 3-arm parallel randomised controlled trial will compare the efficacy of brief guided internet-based therapy to unguided internet-based therapy and to standard care. Approximately 100 participants with FS will be recruited, with diagnostic criteria based on gold standard video-electroencephalogram (v-EEG) monitoring; patients will be randomly assigned to one of the three study arms. The primary study outcome will be FS frequency at 6 weeks and at follow-up (6 and 12 months) compared with baseline. Seizure frequency will be modelled using Poisson regression. Secondary outcomes include psychosocial functioning, healthcare resource usage, anxiety, depression, somatisation and life impact. Between-group differences will be evaluated using analysis of variance. Analysis of covariance will estimate within-group changes on secondary outcomes. Cognitive and psychological factors will be used as predictors of seizure reduction in exploratory analyses. A qualitative survey using a semi-structured interview will use thematic analyses to explore participants' treatment experiences, their impressions of FS management and perceived mechanisms for change. ETHICS AND DISSEMINATION: The study was approved by the Human Research and Ethics Committee of the Alfred Hospital Human Research Ethics Committee as part of the Australian Multisite Ethics approval system. Results of the study will be presented at national and international conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ACTRN12622000262707.

Hospital staff well-being during the first wave of COVID-19: Staff perspectives.

The purpose of this research is to determine the impact of working during the early stage of the COVID-19 pandemic on the well-being of staff at one 600-bed acute hospital in metropolitan Melbourne, Australia. This exploratory study is part of a larger mixed methods survey project, reporting the qualitative data from an on-line survey of clinical staff working at one acute hospital between April 16th and May 13th, 2020 during the COVID-19 pandemic. Responses to five free-text questions were analysed using inductive content analysis. 321 medical, nursing, allied health and non-clinical staff responded to the survey. Respondents reported anxiety, fear and uncertainty related to the pandemic, from the perspectives of work, home, family and community. They reported feeling confused by inconsistent messages received from government, hospital executive, managers and media. Seven themes were identified: (i) worrying about patient care, (ii) changed working conditions, (iii) working in the changed hospital environment, (iv) impact of the pandemic, (v) personal isolation and uncertainty, (vi) leadership and management and (vii) additional support needed for staff. Despite the pandemic being comparatively well-controlled in Australia, all disciplines reported a high degree of anticipatory anxiety. Staff working in healthcare require both managerial and psychological support to minimise anxiety and promote well-being and resilience in order to deal with the health crisis. Regular unambiguous communication directing the way forward is crucial.

The effect of improved dietary control on cognitive and psychiatric functioning in adults with phenylketonuria: the ReDAPT study.

BACKGROUND: Phenylketonuria (PKU) is an autosomal recessive inherited disorder characterised by a deficiency in phenylalanine hydroxylase. Untreated, PKU is associated with a wide range of cognitive and psychiatric sequelae. Contemporary management guidelines recommend lifetime dietary control of phenylalanine (Phe) levels, however many individuals who discontinue dietary control subsequently suffer symptoms of anxiety, depression and disturbances to cognition. We undertook a prospective cohort study of patients with early-treated phenylketonuria who had ceased dietary control to test the hypothesis that resumption of dietary control of PKU is associated with improvements in measures of psychiatric morbidity and cognitive functioning. METHODS: We re-initiated dietary control for early-treated patients with PKU and monitored cognitive and psychiatric outcomes over a twelve-month period. Assessments included objective cognitive function (measured by cognitive proficiency index (CPI)), anxiety and depression scales. General linear mixed model (GLMM) analyses were performed to assess change in psychometric variables from baseline over twelve months after resumption of dietary control. RESULTS: A total of nine patients were recruited. Mean age was 33 years (SD = 8.75), five were female. Mean time off dietary control was 19.1 years (SD = 11.3), and mean baseline phenylalanine (Phe) levels were 1108 µmol/L (SD = 293). GLMM analysis demonstrated a positive relationship between CPI and time on diet (b = 0.56 [95% CI = 0.17, 0.95]). Age, time off diet, Phe levels and depression scores were not associated with cognitive function. There was a negative relationship between time on diet and anxiety (b = - 0.88 95% CI = [- 1.26, - 0.50]) and depression ratings (b = - 0.61, 95% CI = [- 0.95, - 0.26]). CONCLUSIONS: This study demonstrated improvements in cognitive function, anxiety, and depression ratings associated with resumption of dietary control of PKU. Raw Phe levels were not strongly associated with psychiatric or cognitive scores in this cohort. These findings support the importance of lifelong treatment for PKU in improving the cognitive and psychiatric sequelae of the disease.

General Practitioners' management of young people with mental health conditions in Australia.

AIM: Detecting and diagnosing youth mental health issues can be challenging for General Practitioners (GPs) who are often the first to encounter them. One aim of this study was to understand the challenges GPs faced in identifying, treating and referring young people with mental health issues in Melbourne, Australia. A second aim was to identify gaps in GP knowledge and service provision in order to design a service and training program for GPs that addresses those gaps. METHOD: A representative sampling method was used to invite GPs in south-east Melbourne to complete the study survey. Seventy-seven GPs completed the questionnaire consisting of 10 questions in 3 sections. RESULTS: The results showed that GPs who consulted with young people more often had greater levels of confidence in identifying and treating their mental health issues but not referring. Forty-four percent identified the need for training in regards to youth mental health. GPs considered that the most effective care was provided in youth-friendly spaces but tended to primarily refer young people to private providers. CONCLUSION: GPs need access to ongoing professional development and education programs on youth mental health, in particular more severe issues such as psychosis. Specialist youth mental health services such as CYMHS/CAMHS and headspace can offer GPs support in managing mental health issues in young people. However, there is a need to strengthen the link between GPs and specialist youth mental health service. Stronger links between services will ensure young people have timely and increased access to treatment.

Five-fold increased risk of relapse following breaks in antipsychotic treatment of first episode psychosis.

BACKGROUND: A key problem in the management of first episode psychosis is that patients are often reluctant to take antipsychotic medication, especially once their presenting symptoms have resolved. Clinicians may be tempted to trial a 'break in treatment' in such patients. AIM: To assess the impact of interruptions in the antipsychotic treatment of first episode psychosis. METHOD: Treatment adherence and clinical course were assessed during the 18months following presentation in 136 consecutive patients with a first episode of psychosis in 2003-2005 by a systematic retrospective casenote review. Regression analyses were used to examine the time to remission and the risk of relapse in patients who had stopped antipsychotics for one month or more. RESULTS: There were breaks in antipsychotic treatment of ≥1month in more than half of the patients (n=73; 58%). When these occurred before they had recovered (n=22; 17%), the time to remission was almost twice as long as in patients in whom treatment was continuous (t=2.9, P=0.01). Patients in whom treatment was interrupted were 5 times more likely to have relapsed than those in whom it was continuous (p=0.0001, 95%CI 2.1-11). The mean time to relapse following an interruption in treatment was 3months. CONCLUSION: If the treatment of first episode psychosis with antipsychotic medication is stopped for a month or more, remission may be delayed and the risk of relapse following remission may be substantially increased.
